GARDEN-SPRINKLER.

Application filed November 24, 1919.

den-Sprinklers, of which the following is a specification, reference being had therein to the accompanying drawings.

rlfhe invention relates to sprinklers more particularly designed for use in the sprinkling ci? gardens7 and it is the object of the invention to obtain a construction Which may be easily adjusted and Without the necessity of getting into the Wet or mud. To this end the invention consists in the peculiar constructkm7 arrangement and combi-v nation of parts as hereinafter set forth.

In the drawings:

Figure l. is a side elevation of the sprinkler;

lF ig. f2 is a plan view thereof;

Fig. 3 is a vertical section.

inthe sprinkling of gardens itis desirable to have e constriution of sprinkler' that rises fbove the growing plants and which is capable of being introduced between rows.4 lt is also desirableto distribute the Water With uniformity and if the range is necessarily limited, this rrequires adjustment from time to time. lllith my improved construction the sprinkler is in the form of a laterallyrztending perforated arrn7 which is mounted upon vertical standpipe of sui'llcient height to clear the tops of the plants, said standpipe being connected at its base with a laterallyextending supply pipe and being also supvported on a Wheeled base to facilitate its movement in and out from between rows. To uniformly distribute the water the spriir. kier arms are rotatively adjustable about the standpipe and provision is made for eflecting this adjustment from a point beyond the range of the sprinkler, so as to avoid the necessity of getting into the Wet or mud..

In detail, El is a vertical standpipe rising from a base fitting B, which is supported on ground Wheels C engaging an axle D. E is a sprinkler arm at the upper end ot the standpipe A. and which preferably extends radially on opposite sides of said standpipe. F are'extension arms of the sprinkler E. which are connected thereto by fittings which permit of folding when not in use and Specification of Letters Patent.

thereby klimiting the dimensions of the device. Brace Wires I from the extremities of the arm E pass over a strut H to stiifen the sprinkler arm. J is a supplypipe eX- tending laterally from the base fitting B, being detachably jointed by the coupling K at a radialdistance from the standpi e, substantially the saine as the fittings ,n said supply conduit having an extension L beyond the coupling of sufficient length to pass beyond the range of the sprinklers. This supply conduit has a. swivel engagement With the fitting .B and at its opposite end has a swivel engagement with a fitting M upon the hose or other extension conduit leading to the tap. The sprinkler arm E is fixedly attached to the inner conduit N, which passes downward Within the standpipe A 'and has a swivel engagement there` with. O and O are intermeshing bevel gears, or other means, for rotatively connecting the adjacent ends of the conduit J and the conduit N. This connection permits of turning the arm E through the medium of the conduits J and L and as the outer end ot the latter conduit is beyond the range of the sprinkler` this adjustment may be effected Without getting into the wet.,

The fitting B is provided with stuiiing boxes T and P Jfor forming a water tight swivel joint respectively between the con duits l and N and said itting. There is also provision for introducing the bevel gears O and O through orifices normally closed by caps Q and Q and through one of these oriices there may be introduced a def flector member 3., which forms an easy bend for the passage of the Water, and avoids im- ;eding its velocity. To provide access to the stuffing box Pf, the standpipe Ais coupled to the tting B through the medium of spaced arms S bolted, or otherwise secured, to ears T and T. This permits access to the cap P2 of the stufling box P', so that the latter may be tightened as often as necessary to maintain. a Water tight joint. is a ball thrust bearing between the upper end of the standpipe A and the sprinkler arm E. which supports the weight and reduces friction. l l

lllhen the sprinklerl is not in use, the eX- tension arms F are folded, as indicated in dotted lines in Fig. l, and the conduit L is detached from the ronduit J. This makes a comparatively compact structure which may be easily stored. In use, the conduit J. is first coupled to the conduit L, the extension arms F are turned to extend outward, and the conduit L is connected with its supply hose or other connection. rlfhe operator may then use the conduit L as a handle and introduce the standpipe and sprinkler between rows of plants, rolling it to the desired position upon the wheels C. The water is then turned on and will be discharged through jet openings in the arms E and F, sprinkling the plants within its range. From time to time the angle of the arms E and F may be altered by rotating the conduit'L through a suitable handle, such as L', and which through the medium of the bevel gear wheels 0 and 0 will rotate the vertical conduit N. The latter being lixedly connected to the arm E, will turn said arm upon the ball bearing After the area within the range of the swinging arms E and l has been completely sprinkled, the standpipe may be adjusted in position also through the medium of the conduit L and whenever necessary, the device may be re moved from between the rows and re-inserted between two other rows.

What l claim as my invention is:

l. A sprinkler comprising a stand pipe provided at its upper end with an angularly adjustable lateral sprinkler arm, means in which the stand pipe is rotatably supported,Y and a laterally-extending supply pipe journaled in the supporting means o1 the stand pipe and operatively connected to the Stand pipe to turn the latter.

2. A sprinkler comprising a base, a stand pipe journaled therein and provided at its upper end with sprinkler arms, a supply pipe journaled near one end in the base transversely to the stand pipe, and means in the base coupling the supply and stand pipes to turn together on their respective axes.

3. A sprinkler comprising a supporting base, a stand pipe journaled in the base and provided with lateral sprinkler arms above the base, a supply pipe swiveled in the base, the latter forming a coupling between the stand pipe and supply pipe, means' within the base operatively connecting the stand and supply pipes for turning the stand pipe by rotation of the supply pipe, and means forming a swivel engagement for detachably securing the supply pipe to a conduit.

4. A sprinkler, comprising a vertical standpipe, a Vwheeled base for supporting the same, a supply pipe extending laterally from said base and havinga swivel engagement therewith, a conduit having a swivel engagement with the other end of said supply pipe, a sprinkler arm rotatively mounted at the upper end of said standpipe, and a driving connection between said supply pipe and sprinkler arm for rotatively adjusting the latter by the rotation of the former.

5. A sprinkler, comprising a standpipe including a base fitting, a laterally-extending supply pipe having a swiveled engagement with said base litting, a conduit within said standpipe having a swiveled engagement with said base fitting, a sprinkler arm 'connected to the upper end of said last -mentioned conduit, intermeshing bevel gears on the adjacentends of said supply pipe and conduit connected to the sprinkler `arm, and a swiveled engagement between said supply conduit and a supply conduit therefor permitting the rotation of the former to effect a Yrotative adjustment of said sprinkler arm.

6. A sprinkler, comprising a standpipe, a supply pipe having a swivel connection with the base of said standpipe, a sprinkler arm mounted at the upper end of said standpipe, connections between said supply pipe and sprinkler arm for rotatively adjusting the latter by rotation of the former, and an eX- tension arm for said sprinkler arm having a swivel engagement therewith permitting` of folding'.

7. A sprinkler, comprising a standpipe, a fitting at the base thereof provided with a capped orilice, a supply pipe having a swiveled engagement with said fitting, a sprinkler arm mounted at the upper end of said standpipe, a conduit within said standpipe connected to said sprinkler arm, and intermeshing gears engaged respectively with said supply conduit and 'conduit within the standpipe, said gears being insertible within said iitting through the aperture therein when uncapped.

-In testimony whereof I aix my signature.
